RADIOGRAPHMOUNT.

2 or other suitable material may be used in its tin is preferable,because of manufacture,

its combination of lightness and strength.v

The need of some strength in this device is more particularly noticed inthe prongs than elsewhere.

When a radiograph or the like has been mounted upon a suitable piece ofcardboard or other material, by means of one of these devices, the saiddevice serves as a rim or frame for the said radiograph, as well asacting as an attaching means, whereby the radiograph is attached.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts wherever they occur,

Figure 1 is a front elevation;

Fig. 2 is a section on the line 2-2 in Fig. 1, looking in the directionindicated by the arrows; and

Fig. 3 is a top-plan view of the device detached from the cardboard andwith its prongs extended.

To the cardboard l or the like, the rim or frame 2 is attached by meansof the prongs 3, which are simply pushed, through the paper or cardboard1 or similar mounting material.

The radiograph 4 is loosely, but securely and fixedly, held between therim 2 and the cardboard 1, there being a prong 3 on each of the foursides or edges of the radiograph l to prevent the said radiograph frombecoming detached from the card by sliding sidewise. It is held by therim 2 so loosely as not in any wise to injure the radiograph 4i. It canbe readily attached to the card without much handling, because of thefacility with which the rim 2 can be attached to the card by the pointedprongs 3.

The rim 2, for strength, is preferably beaded or bowed as at 5, acorresponding Specification of Letters Patent.

Application filed October 3, 1919. Serial No. 328,089.

groove 6 being formed on the underneath or inside of the rim 2. Also, bybowing the corners of the frame 1, it will be appreciated that the samewill be provided with a greater range of purchase or engaging surface,rendering it possible for the device to effectively retain films thereinwhich vary slightly, as by imperfections, since the reduction in widthof the frame adjacent its end portions will compensate for the saidslight variances in the size of thefilm.

fter the pointed prongs 3 have been pushed through the cardboard 1, theyare bent over as shown in Figs. 1 and 2.

If desired, these rims can be applied by a simple hand pressure machineor by hand.

One advantage of this holder or mount is that it can be made of a sizeexactly to fit dental radiograph films and thus to cover the edges ofthe fihn'and to prevent breaking or tearing of the film by reason ofsuch injuries.

Another advantage is that, as stated above, by reason of the radiographbeing held on four sides, it can not slip loose and thus becomedetached.

Still another advantage is that, if thin celluloid or other transparentor translucent material be used for the mount, the radiograph can beattached in any position thereon. In making X-ray dental photographs, itis necessary to use from one film to ten films for each patient,according to the number of teeth to be displayed. .On account of theshape of the teeth and the curves in the mouth, it is advisable to placethe dental film packet sometimes in a horizontal position and sometimesin a vertical position. Furthermore, it is advisable that all thepictures of the teeth of one patient be mounted together on the samecard or mount and in their relative positions and, also, that thepictures taken in vertical position shall be mounted vertically andthose taken horizontally mounted in a horizontal position. Dental filmmounts now on the market are manufactured with openings to receive thefilm or dental X-ray photograph already cut in the mount, which makes itnecessary that the roentgenologists keep on impossible for him to find amount that will meet his exact requirements. This is ol viated by theuse of the present invention in connection with transparent ortranslucent material for the mount.

Some mounts now 011 the market have projecting edges to catch and holdthe film, but such overlapping edges or projections frequently catch oneach other or some adjacent objects and thereby become bent or broken,which permits the film to become detached from the mount.

From the foregoing, it will be evident that when mounted on anytransparent or translucent material dental radiographs can be attachedthereto by this film-mounter in any position, so that they can beexamined in any position by transmitted light.

paque material can be used for the mount 1 if the operator has at handsuitable means for cutting therein openings or holes in any position orarrangement such as now found in mounts on the market.

Having thus described this invention, I hereby reserve the benefit ofall changes in form, arrangement, order, or use of parts, as it isevident that many minor changes may be made therein without departingfrom the spirit of this invention or the scope of the following claim.

claim:

A radiograph mount comprising a frame substantially -shaped incross-section adapted to receive the outer side, top, and end portionsof the radiograph therein, the edges of which portions are spaced fromthe adjacent rear walls of said frame to compensate for expansion, saidframe havin penetrating prongs extending from the outer marginalportions of its various sides adapted for clenching engagement with asuitable base, the corners of the frame being substantially U-shaped incross-section to provide the same with a greater range of en gagement toinsure connection between the frame and the radiograph upon contractionthereof, and said prongs being arranged intermediate the ends of theframe sides whereby additionally to serve as means for limiting movementof the radiograph with respect to such frame.

In testimony whereof I hereunto aflix my signature.

ARTHUR W. BUCK.
